However, there is room for improving the cut cloth from the following viewpoint. That is to say, bag-shaped portions are formed in the collar portion formed of a cloth so as to allow the rubber cords to be inserted. This provides a structure so as to allow the collar portion to be in contact with the neck of the wearer. Such an arrangement allows the collar portion to adhere to the neck of the wearer due to the elastic force applied by the rubber cords. However, there is room for improving the adhesion between the neck of the wearer and the collar portion. Accordingly, a waterproofing device such as a cut cloth is preferably configured to provide a wearing portion to be worn with improved adhesion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment

Description will be made below with reference to FIGS. 1 and 2 regarding a shampoo cloth 10 configured as a “foreign matter intrusion prevention device” according to a first embodiment. The shampoo cloth 10 is configured as a front-opening waterproof cloth to be used in shampooing. Specifically, a user P to be shampooed puts on the shampoo cloth 10 so as to prevent a liquid or the like from attaching to the clothing of the user P to be shampooed.

The shampoo cloth 10 has an overall structure having an approximately rectangular sheet shape. The shampoo cloth 10 is configured including a wearing portion 20 configured as an approximately central portion of the shampoo cloth 10, a cover portion 30 configured as an outer circumferential portion of the shampoo cloth 10, and a water cut portion 40 configured to surround the wearing portion 20 and to have a size that is smaller than that of the cover portion 30.

The wearing portion 20 is configured as a wearing portion to be worn around the neck NC of a user P to be shampooed. The wearing portion 20 is configured in a shape of an approximately circular band having an opening portion as viewed in the thickness direction of the shampoo cloth 10. Furthermore, the wearing portion 20 is configured including a first wearing member 22 that forms a portion of the wearing portion 20 on one side thereof in the thickness direction (on the side indicated by the arrow A in FIG. 1B, i.e., the front face side) and a second wearing member 24 that forms a portion of the wearing portion 20 on the other side thereof in the thickness direction (on the side indicated by the arrow B in FIG. 1B, i.e., the back face side). The first wearing member 22 and the second wearing member 24 are affixed to each other in the thickness direction.

The second wearing member 24 is formed of a stretchable synthetic rubber material. The synthetic rubber material that forms the second wearing member 24 preferably contains a chloroprene rubber material as a component or a base component, examples of which include neoprene (trademark). Furthermore, the synthetic rubber material that forms the second wearing member 24 preferably has a sponge-like structure.

The first wearing member 22 and the second wearing member 24 are respectively configured of materials having different stretching rates. The first wearing member 22 is configured of a fiber material or a coating film that allows it to easily slip on the surface of the second wearing member 24. Examples of the fiber material that forms the first wearing member 22 includes a knit fabric (jersey fabric) having stretchability. Furthermore, the coating film that forms the first wearing member 22 is configured as a coating agent that can be used to perform surface treatment for a rubber material, and that provides the rubber surface with improved slipperiness. Examples of such a coating agent include a super composite skin coating agent.

That is to say, the wearing portion 20 is configured of two members, i.e., the first wearing member 22 and the second wearing member 24 having a stretchability (stretching rate) that differs from, i.e., that is higher or otherwise lower than, the stretchability (stretching rate) of the first wearing member 22. Specifically, the wearing portion 20 is configured of so-called wetsuit fabric.

Furthermore, the wearing portion 20 is designed to have a width that becomes progressively wider towards the central portion from both ends of the wearing portion 20 along the longitudinal direction thereof. In other words, the width W1 of the wearing portion 20 at both ends thereof in the longitudinal direction is smaller than the width W2 of the wearing portion 20 at the central portion thereof in the longitudinal direction.

Furthermore, a hook-and-loop fastener 26 is provided to the surface of the wearing portion 20 such that it is positioned on an end of the wearing portion 20 on one side in the longitudinal direction thereof. The hook-and-loop fastener 26 is arranged on the inner-side end of the wearing portion 20 along the radial direction thereof such that it extends in the circumferential direction of the wearing portion 20. Furthermore, the hook-and-loop fastener 26 is sewn to the wearing portion 20 (first wearing member 22). On the other hand, a hook-and-loop fastener 28 is provided to the back face of the wearing portion 20 such that it is positioned on the other end of the wearing portion 20 in the longitudinal direction thereof. The hook-and-loop fastener 28 is provided to the inner-side end of the wearing portion in the radial direction thereof such that it extends along the circumferential direction of the wearing portion 20. Furthermore, the hook-and-loop fastener 28 is sewn to the wearing portion 20 (second wearing member 24).

With such an arrangement, the wearing portion 20 allows its radial-direction inner portion of the wearing portion 20 to be wound around the neck NC of a user P to be shampooed. In this state, by affixing the hook-and-loop fastener 26 and the hook-and-loop fastener 28 to each other, this allows the user P to be shampooed to wear the shampoo cloth 10 such that the wearing portion 20 is wound around the neck NC of the user P to be shampooed and such that the wearing portion becomes an approximately cylindrical shape along the outer circumferential face of the neck NC.

The cover portion 30 is configured of a resin sheet member. The cover portion 30 is configured to have an overall structure in an approximately rectangular shape. An opening portion 32 is formed in a central portion of the cover portion 30 in the form of a through hole. The opening portion 32 has a shape that corresponds to the outer shape of the wearing portion 20. With such an arrangement, the outer circumferential portion of the opening portion 32 is sewn to an end of the wearing portion 20 on one side in the width direction (outer side in the radial direction). With this arrangement, the cover portion 30 is arranged such that it extends from the outer end of the wearing portion 20 in the radial direction toward the outer side in the radial direction of the wearing portion 20. Furthermore, a slit 36 is formed at a position that corresponds to both ends of the wearing portion 20 in the longitudinal direction thereof such that it divides the cover portion 30 in the circumferential direction thereof.

The water cut portion 40 is configured of a resin sheet member. The water cut portion 40 is configured to have an overall structure in an approximately rectangular shape with a size that is smaller than that of the cover portion 30. Furthermore, the water cut portion 40 is arranged such that it overlaps the cover portion 30. An opening portion 34 is formed in a central portion of the water cut portion 40 in the form of a through hole. The opening portion 34 has a shape that corresponds to the inner shape of the wearing portion 20. With such an arrangement, the outer circumferential portion of the opening portion 34 is sewn to an end on one side of the wearing portion 20 in the width direction (inner side in the radial direction). With this arrangement, the water cut portion 40 is arranged such that it extends from the inner-side end of the wearing portion 20 in the radial direction toward the outer side in the radial direction of the wearing portion 20. It should be noted that, as with the cover portion 30, the water cut portion 40 may be arranged such that the outer circumferential portion of the opening portion 34 is sewn to the end of the wearing portion 20 on one side in the width direction of the wearing portion 20 (outer side in the radial direction).

The outer circumferential portion of the opening portion 34 is preferably sewn in a loose state to the end on one side in the width direction of the wearing portion 20 (inner side in the radial direction). This arrangement is configured such that it does not prevent the elongation of the wearing portion 20 when the wearing portion 20 is to be elongated in the longitudinal direction before it is wound around the neck NC of the user P to be shampooed. Furthermore, this arrangement allows the water cut portion 40 to be wound around the neck NC without looseness at the time of wearing.

Operation and Effects

Next, description will be made regarding the operation and the effects of the first embodiment.

Before a user P to be shampooed puts on the shampoo cloth 10 configured as described above, the opening portion 12 of the shampoo cloth 10 is opened, and the shampoo cloth 10 is arranged so as to cover the upper body of the user P to be shampooed. Subsequently, the neck NC of the user P to be shampooed is set such that it is within the wearing portion 20. Furthermore, the wearing portion 20 is wound around the neck NC of the user P to be shampooed such that both ends of the wearing portion 20 in the longitudinal direction overlap. Specifically, the wearing portion 20 is set such that it is elongated in the longitudinal direction. Furthermore, the wearing portion 20 is set such that one end of the wearing portion 20 in the longitudinal direction overlaps the other end of the wearing portion 20 in the longitudinal direction. Subsequently, the hook-and-loop fastener 26 and the hook-and-loop fastener 28 are affixed to each other. This allows the wearing portion 20 to be worn such that it is wound in a cylindrical form around the neck NC of the user P to be shampooed. More specifically, the wearing portion 20 is set such that it becomes a cylindrical shape with the second wearing member 24 thereof as its inner circumferential face and such that it adheres to the neck NC of the user P to be shampooed. Furthermore, the wearing portion 20 is set such that it becomes a cylindrical shape with the first wearing member 22 thereof as its outer circumferential face. In this state, the cover portion 30 covers the upper body of the user P to be shampooed (see FIG. 2).

With the wearing portion 20 of the shampoo cloth 10, there is a difference in the stretching rate between the second wearing member 24 and the first wearing member 22. When the wearing portion 20 is wound around the neck NC of the user P to be shampooed, such an arrangement allows the wearing portion 20 to be elongated in the longitudinal direction due to the wearing member having a high stretching rate. This allows the wearing portion 20 to be wound easily around the neck NC of the user P to be shampooed. After the wearing portion 20 is wound around the neck NC of the user P to be shampooed, the wearing portion 20 contracts in the longitudinal direction due to the wearing member having a low stretching rate. This provides the wearing portion 20 with improved adhesion with respect to the user P to be shampooed. By providing the wearing portion 20 with improved adhesion with respect to the user P to be shampooed, this arrangement reduces the potential to cause the occurrence of a gap between the wearing portion 20 and the neck NC of the user P to be shampooed. This arrangement is capable of preventing a liquid such as water, permanent wave solution, shampoo solution, treatment solution, or the like, and solid foreign matter such as hair, from attaching to the clothing of the user P to be shampooed.

Furthermore, the wearing portion 20 of the shampoo cloth 10 is configured such that the first wearing portion and the second wearing portion 24 are affixed to each other in the thickness direction of the wearing portion 20, and the stretching rates of the first wearing portion 22 and the second wearing portion 24 are different. This arrangement provides improved durability to the wearing portion 20 that is to be repeatedly worn such that it is wound around the neck NC of a user P to be shampooed.

That is to say, in a state in which a user P to be shampooed puts on the wearing portion 20, the wearing portion 20 is wound around the neck NC in a cylindrical form while the wearing portion 20 is elongated in the longitudinal direction. Accordingly, in the wearing state of the wearing portion 20, the stretching amount (extension amount) of the portion on one face side of the wearing portion 20 having a higher stretching rate is larger than that of the other face side having a lower stretching rate. In a case in which the wearing portion 20 is configured of only a single member having a higher stretching rate, in some cases, such a member having a higher stretching rate is excessively elongated. Accordingly, this arrangement has the potential to involve degradation of the durability of the wearing portion 20.

In contrast, with the wearing portion 20 according to the present embodiment, as described above, there is a difference in the stretching rate between the first wearing member that functions as the outer circumferential face of the cylindrical wearing portion 20 and the second wearing member that functions as the inner circumferential face thereof in a state in which the user P to be shampooed puts on the wearing portion 20. Accordingly, in a state in which the user P to be shampooed puts on the wearing portion 20, this arrangement allows the stretching amount (extension amount) of the member having a higher stretching rate to be reduced as compared with the above-described arrangement. This arrangement is capable of preventing the member having a higher stretching rate from being excessively elongated. Accordingly, such an arrangement provides the wearing portion 20 with improved durability.

Furthermore, the wearing portion 20 of the shampoo cloth 10 is configured such that the second wearing portion 24 formed of a synthetic rubber material is affixed to the first wearing member 22 formed of a fiber material or otherwise a coating film formed in order to provide the surface of the second wearing member 24 with improved slipperiness. That is to say, the wearing portion 20 is configured of wetsuit fabric. This provides the wearing portion 20 with improved adhesion in a simple manner with respect to a user P to be shampooed.

Furthermore, the shampoo cloth 10 is configured such that the width W1 of the wearing portion 20 at both ends of in the longitudinal direction is smaller than the width W2 of a central portion thereof in the longitudinal direction. This arrangement allows a user P to be shampooed to wear the wearing portion 20 such that it is wound around the neck NC while preventing both ends of the wearing portion 20 in the longitudinal direction from coming in contact with the Adam's apple of the user P to be shampooed. Accordingly, this arrangement provides improved wear comfort when the user P to be shampooed is wearing the shampoo cloth 10.

The first wearing member 22 that functions as the outer circumferential face of the cylindrical wearing portion 20 is configured of a knit fabric or otherwise a coating film formed in order to provide it with improved slipperiness on the surface of the second wearing member 24. This allows the second wearing member 24 to be configured as a quick-drying member. This reduces discomfort due to a wet wearing portion 80. Furthermore, this arrangement enables reduction in the period of time required before the shampoo cloth 10 can be used for the next wearer after the wearing portion becomes dry after it is used for the previous wearer. Furthermore, by configuring the first wearing member 22, which functions as the outer circumferential face of the cylindrical wearing portion 20, of a coating film formed in order to provide it with improved slipperiness on the surface of the second wearing member 24, this arrangement is capable of preventing hair or dust from adhering to the second wearing member 24.

Second Embodiment

Description will be made with reference to FIGS. 3 and 4 regarding a shampoo cloth 50 configured as a “foreign matter intrusion prevention device” according to a second embodiment. The shampoo cloth 50 has the same configuration as that of the shampoo cloth 10 according to the first embodiment except for a wearing portion 60. It should be noted that, in the drawings, each member having the same configuration as that according to the first embodiment is denoted by the same reference numeral.

With the second embodiment, the wearing portion 60 is formed in a long band shape, and is configured such that it is folded back at a central portion thereof in the width direction and such that it is bent in an approximately cylindrical form having an opening portion. Specifically, as shown in FIG. 4, in an extended state of the wearing portion 60, the wearing portion 60 is configured including a first wearing member 22 that forms a portion on one side of the wearing portion 60 in the width direction and a second wearing member 24 that forms another portion on the other side of the wearing portion 60 in the width direction. An edge of the second wearing member 24 on one side in the width direction is sewn to an edge of the first wearing member 22 on the other side in the width direction. With such an arrangement, a portion of the second wearing member 24 thus sewn will be referred to as a “sewn portion 62”. It should be noted that the wearing portion 60 may be configured such that the second wearing member 24 is affixed to the other side of the first wearing member 22 in the thickness direction and such that the first wearing member 22 is affixed to the other side of the second wearing member 24 in the thickness direction. Also, the wearing portion 60 may be configured of a portion on one side thereof in the width direction in which the second wearing member 24 is affixed to and sandwiched by the first wearing member 22 in the thickness direction and another portion on the other side thereof in the width direction in which the first wearing member 22 is affixed to and sandwiched by the second wearing member 24 in the thickness direction.

With the second embodiment, as shown in FIGS. 3A and 3B, the wearing portion 60 is folded back along the sewing portion 62 so as to arrange the first wearing member 22 and the second wearing member 24 such that they face each other in the thickness direction. Subsequently, the wearing portion 60 is bent in a cylindrical form having an opening portion. Specifically, the wearing portion 60 is bent such that the second wearing member 24 functions as the inner circumferential face of the cylindrical wearing portion 60, and such that the first wearing member 22 functions as the outer circumferential face of the cylindrical wearing portion 60.

The cover portion 30 and the water cut portion 40 are sewn to one end of the wearing portion 60 in the width direction thereof such that they extend from the wearing portion 60. With such an example shown in the drawing, the cover portion 30 and the water cut portion 40 are sewn to the inner side of the first wearing member 22 that functions as the outer circumferential face of the wearing member 60. Also, the cover portion 30 and the water cut portion 40 may be sewn to the inner side of the second wearing member 24 that functions as the inner circumferential face of the wearing member 60. Also, an arrangement may be made in which the cover portion 30 is sewn to the inner side of the second wearing member 24 that functions as the inner circumferential face of the wearing member 60, and the water cut portion 40 is sewn to the inner side of the first wearing member 22 that functions as the outer circumferential face of the wearing member 60. Also, as with the first embodiment, an arrangement may be made in which the cover portion 30 is sewn to one end of the wearing portion 60 in the width direction thereof and the water cut portion 40 is sewn to a width-direction upper portion of the outer side of the first wearing member 22 that functions as the outer circumferential face of the wearing portion 60 such that it is positioned in the vicinity of the sewn portion 62.

Furthermore, as shown in FIG. 4, the first wearing member 22 is designed such that both ends thereof in the longitudinal direction have a width W3 that is smaller than a width W4 at a central portion thereof in the longitudinal direction. The second wearing member 24 is designed such that both ends thereof in the longitudinal direction have a width W5 that is smaller than a width W6 at a central portion thereof in the longitudinal direction. In addition, the width W6 of the central portion of the second wearing member 24 is designed to be larger than the width W4 of the central portion of the first wearing member 22 in the longitudinal direction.

Furthermore, a hook-and-loop fastener 26 is provided to the outer circumferential face of the wearing portion 60 (first wearing member 22) such that it is positioned at an end on one side thereof in the longitudinal direction. In addition, a hook-and-loop fastener 28 is provided to the inner circumferential face of the wearing portion 60 (second wearing member 24) such that it is positioned at an end on the other side thereof in the longitudinal direction.

With such an arrangement, when a user P to be shampooed puts on the shampoo cloth 50, in the same manner as in the first embodiment, the wearing portion 60 is elongated in the longitudinal direction (circumferential direction). Furthermore, the wearing portion 60 is wound around the neck NC of the user P to be shampooed such that both ends of the wearing portion 60 in the longitudinal direction overlap. Subsequently, the hook-and-loop fasteners 26 and 28 are affixed to each other. In this state, the user P to be shampooed puts on the wearing portion 20 such that it is wound around the neck NC of the user P to be shampooed in a cylindrical form.

As described above, when the wearing portion 60 is wound around the neck NC of the user P to be shampooed and after the wearing portion 60 is wound around the neck NC of the user P to be shampooed, the wearing portion 60 is folded back along the sewn portion 62. In this state, the first wearing member 22 and the second wearing member 24 are arranged such that they face each other in the thickness direction. That is to say, in this state, the first wearing member 22 and the second wearing member 24 having different stretching rates are arranged such they overlap in the thickness direction. Accordingly, with the second embodiment, this arrangement also allows the wearing portion 60 to be easily wound around the neck NC of the user P to be shampooed. Furthermore, this arrangement provides the wearing portion 60 with improved adhesion with respect to the user P to be shampooed.

Furthermore, with the second embodiment, the wearing portion 60 is folded back along a central portion (sewn portion 62) in the width direction such that the wearing portion 60 is bent in a cylindrical form. Accordingly, with the second embodiment, the wearing portion 60 is configured to allow the first wearing member 22 and the second wearing member 24 to be relatively moved in the circumferential direction of the wearing portion 60. This arrangement is capable of preventing the second wearing member 24 from deviating with respect to the neck NC of the user P to be shampooed even if the first waring member 22 deviates in the circumferential direction of the wearing portion 60 in shampooing for the user P to be shampooed. Accordingly, this arrangement provides the wearing portion 60 with improved adhesion with respect to the neck NC.

In addition, the wearing portion 60 is wound around the neck NC of the user P to be shampooed in a state in which the first wearing member 22 and the second wearing member 24 having different stretching rates overlap. This arrangement provides improved durability to the wearing portion 60 that is to be repeatedly worn such that it is wound around the neck NC of a user P to be shampooed.

Furthermore, the width W6 of the central portion of the second wearing member 24 in the longitudinal direction is designed to be larger than the width W4 of the central portion of the first wearing member 22 in the longitudinal direction. Accordingly, when a user P to be shampooed puts on the wearing portion 20 such that it is wound around the neck NC of the user P to be shampooed, this arrangement is capable of preventing a folded-back portion of the wearing portion 20 from coming in contact with the nape of the neck of the user P to be shampooed. This arrangement provides the wearing portion 20 with further improved wear comfort for the user P to be shampooed. Furthermore, this arrangement allows the user P to be shampooed in a simple manner.

Third Embodiment

Description will be made with reference to FIGS. 5 and 6 regarding a shampoo cloth 70 configured as a “foreign matter intrusion prevention device” according to a third embodiment. The shampoo cloth 70 has the same configuration as that of the shampoo cloth 50 according to the second embodiment except for a wearing portion 80. It should be noted that the overall structure of the shampoo cloth 70 shown in a plan view according to the third embodiment is the same as that of the shampoo cloth 50 according to the second embodiment except for the reference numerals. Accordingly, detailed description thereof will be omitted. Also, in the drawings, each member having the same configuration as that according to the second embodiment will be denoted by the same reference numeral.

With the third embodiment, as shown in FIGS. 5A and 5B, when a user P to be shampooed puts on the shampoo cloth 70, the wearing portion 80 formed in a long band shape is folded back along a central portion 82 in the width direction such that it is bent in an approximately cylindrical form having an opening portion. The wearing portion 80 is configured such that a second wearing member 24 is affixed to the other side portion of the first wearing member 22 in the thickness direction. The wearing portion 80 is folded back along the central portion 82 in the width direction such that the first wearing member 22 is on an outer side and the second wearing member 24 is on an inner side. Furthermore, the wearing portion 80 is bent in a cylindrical form having an opening portion. In such a state in which the wearing portion 80 is bent in a cylindrical form, the first wearing member 22 becomes both the inner circumferential face and the outer circumferential face of the wearing portion 80 formed in a cylindrical form.

Furthermore, as shown in FIG. 5A, the wearing portion 80 has the same external shape and the same widths as those of the wearing portion 60 according to the second embodiment. Furthermore, a hook-and-loop fastener 26 is provided to the outer circumferential face (first wearing member 22) of the wearing portion 80 such that it is positioned at an end thereof on one side in the longitudinal direction. On the other hand, a hook-and-loop fastener 28 is provided to the inner circumferential face (first wearing member 22) of the wearing portion 80 such that it is positioned at an end thereof on the other side in the longitudinal direction.

When a user P to be shampooed puts on the shampoo cloth 70, the wearing portion 80 is folded back along the central portion 82 in the width direction such that the first wearing member 22 is on an outer side and the second wearing member 24 is on an inner side. In this state, the wearing portion 80 is elongated in the longitudinal direction (circumferential direction) in the same manner as in the second embodiment. Subsequently, the wearing portion 80 is wound around the neck NC of the user P to be shampooed such that both ends of the waring portion 80 in the longitudinal direction overlap. Furthermore, the hook-and-loop fasteners 26 and 28 are affixed to each other. In this state, the user P to be shampooed puts on the wearing portion 80 such that it is wound around the neck NC in a cylindrical form. In this stage, the first wearing member 22 of the wearing portion 80 becomes an outer side of the cylindrical form, and becomes an inner circumferential face and an outer circumferential face of the wearing portion 80. On the other hand, the second wearing member 24 becomes an inner side of the cylindrical form.

As with the first embodiment, the wearing portion 80 is configured of two members having different stretching rates. The wearing portion 80 also provides improved ease of winding, improved adhesion, and improved durability. Furthermore, with the third embodiment, the wearing portion is configured such that the second wearing member 24 functions as an inner side of a cylindrical form. This arrangement prevents the wearing portion 80 from deviating with respect to the neck NC due to friction between the opposing portions of the second wearing member 24 that functions as an inner side of the cylindrical form. Accordingly, this arrangement provides the wearing portion 60 with further improved adhesion with respect to the neck NC.

In particular, by configuring the first wearing member 22 as a knit fabric or a coating film formed in order to provide improved slipperiness on the surface of the second wearing member 24, the first wearing member 22 is configured as a quick-drying member. By configuring the inner side of the cylindrical structure in addition to the outer side thereof as the quick-drying first wearing member 22, this arrangement reduces discomfort due to a wet wearing portion 80. Furthermore, by configuring the first wearing member 22 as a coating film formed in order to provide improved slipperiness on the surface of the second wearing member 24, this arrangement is capable of further preventing hair and dust from adhering to the second wearing member 24.

With the third embodiment, a cover portion 30 and a water cut portion 40 are each sewn to an end of the wearing portion 80 in the width direction such that they extend from the wearing member 80 in the same manner as in the first embodiment. In the same manner as in the second embodiment, as shown in FIG. 5B, both the cover portion 30 and the water cut portion 40 may be sewn to the second wearing member 24 on the inner side of the outer circumferential face of the wearing portion 80. Also, both the cover portion 30 and the water cut portion 40 may be sewn to the second wearing member 24 on the inner side of the inner circumferential face of the wearing portion 80. Also, an arrangement may be made in which the cover portion 30 is sewn to an end of the second wearing member 24 in the width direction on the inner side of the inner circumferential face of the wearing portion 80, and the water cut portion 40 is sewn to an end of the second wearing member 24 in the width direction on the inner side of the outer circumferential face of the wearing portion 80. Also, in the same manner as in the first embodiment, an arrangement may be made in which the cover portion 30 is sewn to an end of the wearing portion 80 in the width direction, and the water cut portion 40 is sewn to an upper portion of the first wearing member 22 on the outer side of the outer circumferential face of the wearing portion 80 such that it is positioned in the vicinity of the central portion 82 in the width direction.

As shown in FIG. 6, the wearing portion 80 may be folded back along the central portion 82 in the width direction such that the first wearing member 22 becomes the outer side and the second wearing member 24 becomes the inner side. In this state, the outer circumferential face and the inner circumferential face of the wearing portion 80 may be sewn to each other in a state in which the wearing portion 80 is bent in a cylindrical form having an opening portion. The portion of the second wearing member 24 thus sewn will be referred to as a “sewn portion 84” hereafter. The sewn portion 84 is sewn in a zigzag form such that it does not impede the stretchability of the first wearing member 22 and the second wearing member 24. This arrangement does not require the wearing portion 80 to be folded back along the central portion 82 in the width direction every time a user puts on the wearing portion 80. It should be noted that the sewn portion 84 may function as a sewn portion to which at least one from among the cover portion 30 and the water cut portion 40 is sewn. Also, the cover portion 30 and the water cut portion 40 may be sewn to the wearing portion 80 at a position that differs from the sewn portion 84.

Fourth Embodiment

Description will be made with reference to FIGS. 7 and 8 regarding a shampoo cloth 90 configured as a “foreign matter intrusion prevention device” according to a fourth embodiment. The shampoo cloth 90 is configured as a back-opening waterproof cloth to be used in shampooing in a hair salon or the like. Specifically, a user P to be shampooed puts on the shampoo cloth 90 so as to prevent a liquid or the like from attaching to the clothing of the user P to be shampooed.

The shampoo cloth 90 is configured to have an overall structure in an approximately rectangular shape. The shampoo cloth 90 is configured including a wearing portion 100 that forms an approximately central portion of the shampoo cloth 90 and a cover portion 110 that functions as an outer circumferential side portion of the shampoo cloth 90. It should be noted that, in the present embodiment, the shampoo cloth 90 may include no water cut portion. Also, the shampoo cloth 90 may include a water cut portion. Also, the shampoo cloth 90 may include no cover portion 110. That is to say, the shampoo cloth 90 may be configured as a so-called neck shutter formed of the wearing portion 100 alone. In the drawings, each member having the same configuration as that in the first embodiment is denoted by the same reference numeral, and detailed description thereof will be omitted.

The wearing portion 100 is configured to be worn such that it is wound around the neck NC of a user P to be shampooed. The wearing portion 100 is configured in a spiral shape arranged such that it extends coaxially as viewed in the thickness direction of the shampoo cloth 90. The wearing portion 100 is designed to have a width that becomes progressively wider in a first phase and becomes progressively narrower in a second phase towards a central portion thereof in the longitudinal direction from one end side of the wearing portion 100 positioned on the inner side of the spiral structure thereof (which will be referred to as the “one-side end” hereafter). Furthermore, the wearing portion 100 is designed to have a width that becomes progressively wider towards an end thereof on the other side in the longitudinal direction positioned on the outer side of the spiral structure thereof (which will be referred to as the “other-side end” hereafter) from the central portion in the longitudinal direction.

In other words, the wearing portion 100 is configured such that the width W7 of the one-side end and the width W9 of the central portion thereof in the longitudinal direction are each smaller than the width W8 at an intermediate position between the one-side end and the central portion in the longitudinal direction. Furthermore, with the wearing portion 100, the width W10 of the other-side end thereof is larger than the width W9 of the central portion in the longitudinal direction. The wearing portion 100 is preferably designed such that the width W7 of the one-side end thereof is smaller than the width W10 of the other-side end thereof. Furthermore, as shown in FIG. 7, the wearing portion 100 is preferably designed such that the one-side end and the other-side end each have a tapered shape having a width that becomes progressively thinner towards its end. This arrangement reduces an area where the one-side end and the other-side end of the wearing portion 100 overlap. This arrangement reduces the potential to cause discomfort for the user P to be shampooed due to the thickness that occurs when the one-side end and the other-side end overlap.

The wearing portion 100 is configured such that its inner-side portion in the radial direction is to be wound around the neck NC of a user P to be shampooed, and the hook-and-loop fasteners 26 and 28 are to be affixed to each other. In this state, the wearing portion 100 is worn such that it is wound around the neck NC of the user P to be shampooed in an approximately cylindrical structure that surrounds the outer circumferential face of the neck NC. In this stage, as shown in FIG. 8, the hook-and-loop fasteners 26 and 28 are affixed to each other at a shoulder portion of the user P to be shampooed.

The cover portion 110 is configured of a resin sheet member having an overall structure in an approximately rectangular shape. An opening portion 112 is formed as a through hole as a central portion of the cover portion 110. The opening portion 112 is configured to have a shape that corresponds to approximately a shape obtained by removing the other-side end of the wearing portion 100 that is to overlap the one-side end thereof from the external shape of the wearing portion 100, i.e., obtained by removing a portion including the hook-and-loop fastener 28 from the external shape of the wearing portion 100. Furthermore, an outer circumferential edge portion of the opening portion 112 is sewn to an end of the wearing portion 100 on one side in the width direction (outer side in the radial direction). With this, the cover portion 110 is arranged such that it extends toward the outer side in the radial direction of the wearing portion 100 from the end of the wearing portion 100 on the outer side in the radial direction. Furthermore, the cover portion 110 is configured such that both ends thereof in the longitudinal direction are to overlap on the back side of the user P to be shampooed. The overlap width for the cover portion 110 is designed to be smaller than the overlap width designed for the overlap of the one-side end and the other-side end of the wearing portion 100.

With such an arrangement, when a user P to be shampooed puts on the shampoo cloth 90, the wearing portion 100 is elongated in the longitudinal direction (circumferential direction) in a state in which a central portion of the wearing portion 100 in the longitudinal direction is set in the vicinity of the Adam's apple of the user P to be shampooed. Furthermore, the wearing portion 100 is wound around the neck NC of the user P to be shampooed such that both ends of the wearing portion 100 in the longitudinal direction overlap. Subsequently, the hook-and-loop fasteners 26 and 28 are affixed to each other. With this arrangement, the overlap portion of the hook-and-loop fasteners are set on a shoulder side of the user P to be shampooed. Accordingly, even in a case in which the shampoo cloth 90 is configured as a back-opening shampoo cloth, this arrangement allows the wearing portion 100 to be wound in a cylindrical form around the neck NC of the user P to be shampooed without involving discomfort for the user P to be shampooed.

As described above, the wearing portion 100 is configured of two members having different stretching rates. Accordingly, with the fourth embodiment, this arrangement also allows the wearing portion 100 to be easily wound around the neck NC of the user P to be shampooed. Furthermore, this arrangement provides the wearing portion 100 with improved adhesion with respect to the user P to be shampooed. In addition, with the fourth embodiment, the wearing portion 100 is wound around the neck NC of the user P to be shampooed in a state in which the first wearing member 22 and the second wearing member 24 having different stretching rates are affixed to each other in the thickness direction. Accordingly, this arrangement provides improved durability to the wearing portion 100 that is to be repeatedly worn such that it is wound around the neck NC of the user P to be shampooed.

Furthermore, the wearing portion 100 is designed such that the width of a central portion thereof in the longitudinal direction is smaller than the widths at the one-side end and the other-side end. This prevents the wearing portion 100 from coming in contact with the Adam's apple of the user P to be shampooed when the user P to be shampooed is wearing the wearing portion 100. This provides improved wear comfort when the user P to be shampooed is wearing the shampoo cloth 90.

It should be noted that description has been made in the first, second, and third embodiments with reference to examples of a so-called back shampoo cloth or a double cape in which the wearing portion 20, 60, or 80, the cover portion 30, and the water cut portion 40 are applied to the shampoo cloth 10. However, the foreign matter intrusion prevention device is not restricted to such an example. For example, the present invention may be applied to a so-called single cape, cut cloth, or collar cloth including no water cut portion 40. Also, the present invention may be applied to a so-called neck cover configured of only the wearing portion 20, 60, or 80 without including both the cover portion 30 and the water cut 40.

Also, the foreign matter intrusion prevention device may be applied to raincoats for people, raincoats for animals, gloves, boots, cast covers, aprons for dining, etc. In any example, this arrangement provides the wearing portion 20, 60 or 80 with improved adhesion with respect to a wearing target. This reduces the potential to cause the occurrence of a gap between the wearing portion 20 and the wearing target, thereby preventing a liquid, foreign solid matter, or the like, from intruding via the gap. In this case, the portion for which the wearing portion 20, 60, or 80 is to be set may be changed as appropriate.

In the first, second, third, and fourth embodiments, the thicknesses and the widths of the wearing portion 20, 60, 80, and 100 are not specified. Rather, the thicknesses and the widths of the wearing portion 20, 60, 80, and 100 may be set as appropriate.

Description has been made in the first, second, third, and fourth embodiments regarding an arrangement in which the hook-and-loop fasteners 26 and 28 are provided to the wearing portion 20, 60, 80, or 100 such that the wearing portion 20, 60, 80, or 100 is fastened around the neck NC of a user P to be shampooed by the hook-and-loop fasteners 26 and 28. However, the configuration for fastening the wearing portion 20, 60, 80, or 100 is not restricted to such an arrangement. For example, instead of the hook-and-loop fasteners 26 and 28, the wearing portion 20, 60, 80, or 100 may be provided with a button, hook, or the like such that the wearing portion 20, 60, 80, or 100 is fastened around the neck NC of the user P to be shampooed by the button, hook, or the like.

Description has been made in the first, third, and fourth embodiments regarding an arrangement in which the wearing portion 20, 80, or 100 is configured such that the first wearing member 22 and the second wearing member 24 are affixed to each other in the thickness direction of the wearing portion 20, 80, or 100. Also, the first wearing member 22 and the second wearing member 24 may be affixed to each other in the thickness direction with the second wearing member 24 sandwiched by the first wearing member 22. Also, the first wearing member 22 and the second wearing member 24 may be affixed to each other in the thickness direction with the first wearing member 22 sandwiched by the second wearing member 24.

In a case in which the first wearing member 22 and the second wearing member 24 may be affixed to each other in the thickness direction with the second wearing member 24 sandwiched by the first wearing member 22, as with the third embodiment, when a user P to be shampooed puts on the wearing portion 20, 80 or 100, the wearing portion is in contact with the neck NC of the user P to be shampooed via the first wearing member 22 configured as a knit fabric, thereby providing an improved feel of the fabric. Furthermore, the knit fabric is configured as a quick-drying member. Accordingly, even if the wearing portion 20, 80 or 100 becomes wet, the wearing portion readily becomes dry quickly. This reduces discomfort due to a wet wearing portion 20, 80, or 100. Furthermore, this arrangement enables reduction in the waiting period of time required before the shampoo cloth can be used for the next wearer after the wearing portion becomes dry after it is used for the previous wearer.

On the other hand, in a case in which the first wearing member 22 and the second wearing member 24 are affixed to each other with the first wearing member 22 sandwiched by the second wearing member 24 in the thickness direction, the outer circumferential face of the wearing portion 20, 80, or 100 is configured as the second wearing member 24 formed of a rubber material. This arrangement is capable of preventing solid foreign matter such as hair or the like from adhering to the outer circumferential face of the wearing portion 20, 80, or 100. Even if such foreign matter adheres to the outer circumferential face of the wearing portion, by brushing or shaking the wearing portion, this arrangement allows such solid foreign matter or the like to be easily removed, thereby allowing the wearing portion to be kept clean.
